The increasing demands for rapid production have significantly boosted the use of CNC systems in industries. Over the past decade, efforts have concentrated on improving the time efficiency and accuracy of CNC machines. . This is also a type of five-axis CNC machine tools with a very wide range of applications. Its price is in the middle, and the size, accuracy and performance of the machine vary greatly. A five-axis CNC machine tool with a double-swing head structure, so the size of the double-swing head itself is not easy to make small, generally 400～500 mm. A typical CNC mill machine tool is shown in Figure 2 below: Xometry CNC machine tools. 4. Driving System. The driving system refers to the motors that move the tool along the various machine axes. In the case of a standard CNC mill, the bed is moved horizontally along the x- and y-axes and the cutting tool is moved up and down along the z-axis.

In comparison to conventional machine tools, CNC machine tool structures have undergone significant changes. They commonly employ features like ball screws and rolling guides, which provide lightweight, precise, and efficient transmission. These structures eliminate backlash through the use of rolling guides or plastic-coated guides. In short, when choosing a C-frame structured machine, look for the widest frame that provides the widest support possible for the X-axis travel to ensure a sturdy-built machine tool. Another consideration when exploring a C-frame machine tool is the guideways that are being deployed. There are two well-known guideways: linear guides and box ways.
